Why wouldn’t this smart newbie learn more?
Many things are competing for his time.
I mean, in an alternate universe, the CIPM and or their predecessors might have liked soccer (cf. Ice-9) very much and called the unit of mass the ‘football’ instead of the ‘(kilo)gram’. In that universe, “the unit of mass is called footballs” would be a perfectly reasonable sentence (not a non-sequitur) that doesn’t prevent (SI) measurement newbies from learning more about the other SI units – the units don’t need to share a name with SI.
While reality is indeed a fiction, it is a shared fiction. That's why the list type is "list", the unit of mass is "kilogram", etc.
Alternate universes are a distinct hobby. In programming, that hobby is represented by esoteric languages.
